Question

1. one microliter serum is added to 6 μl diluent. give the dilution of the solution. what is the serum - total volume ratio

Explanation:

Step1: Calculate total volume

The volume of serum is $1\ \mu L$ and the volume of diluent is $6\ \mu L$. The total volume $V_{total}=1 + 6=7\ \mu L$.

Step2: Calculate serum - to - total volume ratio

The ratio of serum to total volume $r=\frac{V_{serum}}{V_{total}}$. Substituting $V_{serum} = 1\ \mu L$ and $V_{total}=7\ \mu L$, we get $r=\frac{1}{7}$.

Answer:

$\frac{1}{7}$
